Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe

Other management
• RFC854 Telnet (menu-driven configuration)
• SSH and Telnet management
• Telnet client
• SSL security for web user interface
• Switch audit log
• DHCP client
• BOOTP
• Simple Network Time Protocol (SNTP)

Security Features

IEEE 802.1X

802.1X - RADIUS authentication; MD5 encryption

ACLs
• Differentiated services code point (DSCP)/IP precedence-based class of service (CoS)
• IPv6 traffic-class-based CoS
• IP address
• Subnet mask
• Protocol
• Service type
• MAC address
• VLAN ID
• TCP/ User Datagram Protocol (UDP) port

Availability

Link aggregation
• Link aggregation using IEEE 802.3ad LACP
